Per Diem at 43 Sutter St, San Francisco, California.

This place is a hidden gem. I was on my way somewhere else and I walked by. You can't really see inside but I saw some good looking people walking in so I took a peek inside. This place was rocking on a Thursday at 4:45 PM. The restaurant and bar was full of 30 something professionals having drinks, work meetings and a good time. I had time to kill and I felt very comfortable sitting at the bar by myself.

Just a really really cool vibe. The happy hour wine was great - a Pinot. Mussels were very good, avocado toast and lobster fries (yup) looked phenomenal. Friendly bartenders. Seemed like quite a few locals - love this place.
